3. Linking Multiple Sets
The Atomi Smart app allows you to link and control multiple string light sets. While the product description states "LINKABLE UP TO 1728FT.", please note that some users have reported that the physical product may not include a female connector for direct daisy-chaining of power. Control linking is primarily done through the Atomi Smart app by grouping devices.

- Create Group: Select the option to create a new group and add all desired Atomi Smart String Lights to this group.
- Synchronized Control: Once grouped, you can control all lights in the group simultaneously for synchronized color changes, brightness adjustments, and scene activations.
Maintenance
- Cleaning: Disconnect the lights from power before cleaning. Wipe bulbs and cord with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Bulb Replacement: The bulbs are designed to be durable and shatterproof. If a bulb needs replacement, contact Atomi Smart customer support for guidance. Do not attempt to replace bulbs with non-Atomi Smart components.
- Storage: If storing the lights for an extended period, coil them neatly and store in a cool, dry place away from direct sunlight.
- Inspection: Periodically inspect the cord and bulbs for any signs of damage, wear, or loose connections. Discontinue use if any damage is found and contact customer support.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power; loose connection; app issue. | Ensure lights are securely plugged into a working outlet. Check the app to confirm the lights are not turned off. Try a different outlet. |
| Cannot connect to Wi-Fi. | Incorrect Wi-Fi band (not 2.4GHz); wrong password; lights not in pairing mode; weak signal. | Ensure your phone is connected to a 2.4GHz Wi-Fi network. Double-check your Wi-Fi password. Follow app instructions to put lights into pairing mode. Move lights closer to your Wi-Fi router. |
| Voice control not working. | Accounts not linked; device not discovered; incorrect commands. | Verify that your Atomi Smart account is correctly linked to Alexa/Google Assistant. Ask your voice assistant to "Discover devices." Use the exact device name configured in the Atomi Smart app. |
| Lights flicker or behave erratically. | Unstable power; Wi-Fi interference; software glitch. | Unplug the lights for 30 seconds and plug them back in. Check for Wi-Fi interference. Ensure the Atomi Smart app is updated to the latest version. |
| Cannot physically link multiple strands. | Product design may not include a female end connector for daisy-chaining power. | The "linkable" feature primarily refers to app control and grouping. Each strand may require its own power source. If physical linking is critical, verify product specifications or contact Atomi Smart support before purchase. |
